i found this website in the net. He builds trombones, valve ophicleide and corno da caccia.

Oh yes, I love his corni da caccia. They are continuations of the Syhre corni da caccia, which I've always thought were some of the most beautiful instruments ever made. They were supposed to be amazing players too, probably only maybe equaled by the Thein corno da caccia. Getting one from Takao is on my short list when I can one day justify buying a corno da caccia. The only unfortunate thing is that he only makes it in Bb, and not the Bb, C, and D that Syhre made them in.

The valved ophicleide is intriguing too, but...I always forgot about it in the shadow of the Syhre stuff.

He wrotes on his facebook site:

"Since 2014 I have taken over the "F.Syhre" workshop."

Those look very well made! Glad to see that an old workshop was taken over by someone with respect for the craft.
